Ph.D. Assistanship Stable Isotope Plant Ecophysiology

[Behzad Mortazavi]

A Ph.D. Graduate Assistantship is available in the Department of  
Biological Sciences at the
University of Alabama to work on an interdisciplinary project at  
Toolik Lake Arctic Research Station (www.uaf.edu/toolik).  The  
student’s research interests should focus on application of stable  
isotopes to plant ecophysiology, ecosystem physiology, or plant  
ecology.  The project will focus on developing a comprehensive  
understanding of winter physiological processes for two tundra
ecosystems.  The student will have the opportunity to interact with  
scientists from the University
of Alabama, Florida International University and the Arctic LTER.  
Working knowledge of stable
isotope ratio mass spectrometry is required and familiarity with LI-
COR photosynthetic and
Campbell Scientific equipments is a plus.

Northern latitudes are thought to be sequestering CO2 emitted from  
anthropogenic activities.
However, the status of these ecosystems as a global sink of C in the  
future hinges upon the
physiological responses of ecosystem components to changes in  
climate.  There is overwhelming
evidence for rapid climate change in the Arctic. Changes include the  
physical environment,
changes in carbon balance, vegetation change. Furthermore, warming in  
the high latitudes is
predicted to predominantly occur in the winter, and climate data  
support that prediction.
However, the vast majority of research on tundra vegetation has  
focused on physiological
processes during the short 2-3 month growing season, with only a  
handful of studies of
physiological processes during the 9-10 month cold season.  Although  
the rates of these
processes are low, summed over the long cold season they are extremely  
important. A
comprehensive understanding of cold-season physiological processes of  
tundra vegetation is
critically needed given the large potential for further climate  
changes in the Arctic.

This is a fully funded assistantship that includes: stipend, health  
insurance, travel and living
accommodations during the research season at Toolik Lake.  Interested  
students should email
pdfs of 1) a current Curriculum Vita, 2) statement of research  
interest, 3) names, phone number
and email addresses of three references as well as 4) an unofficial  
copy of transcripts to Dr.
